memory system Flashcards
what happens in the memory system
all sesnes feed lots to the CNS
this means the layer can switch attention
where is the info held
shot term sensory store
each sense has a store
coded message for each stimulus compared to info held in long term in order to identify it
sensory memory held in STSS fades and is lost, happens before we conscious
what are the different stages in the memory model
STSS
short term memory
decision making
what happens on the stss stage of the memeory model
area of the brain that receives info and holds it for a short time prior processing
what happens in the short term memory stage of thr memory model
keeps info for 20-30 secs after it is deemed worthy info, cam separate into 5-9 sections of info
what happens in the decision making stage of the memory model
decides what to do or passed on info to the long term memory for permanent storage
what happens in the long term memory stage in the memory model
retains info for long time, not forgotten but can require a code for the info to be recalled
what is reaction time
time between the onset of stimulus to the start of a response.
what is response time
time it takes to process info and then make a response
what is the equation for response time
response time = reaction time + movement time
what is movement time
time it takes to complete onset of movement
what does hicks law suggest
if several stimuli are given only one must be selected for a response.
choice must be made of which stimuli to respond to
more choices a person has the more info needs processing and the longer it takes
factors affecting reaction time
age
gender
height
stimulus intensity
arousal level
anticipation
importance
implication of reaction time to the coach
suitable selection of sport
reaction speed drills
work on set pieces
proper warm up
levels of motivation
what happens in psychological refraction period
PRP is what happens when following an intital stimulus there is presentation of. second stimulus
PRP is the time lag that occurs in responding to the second stimuli, because first was still processing causes slowing down of the processing
what is the single channel theory
suggests that a performer can only attend t one thing at a time
info is processed sequentially one after the other
how does attentional switching occur in the single channel theory
by transferring attention from one situation to another
can only be done if each situation requires small attentional capacity
what is anticipation
abaility to predict future events from early signals
what is temporal anticipation
pre judging where and when future event will be
how does anticipation affect performance
RT can be sped up if performer can learn to anticipiate certain actions
good performers start running motor program before stimulus is fully recognised
how to improve response time
detection of the cue- stimulus is sorted from back ground noise
decision making
concentration
controlling anxiety
warm up
what is schmidts schema theory
sports performers can undertake so many actions with very little concious control.
LTM isnt big enough to store all motor programs required
WHAT DOES THE SCHMIDTS THEORY SUGGEST
generalised motor programs exist which can be modified by taking in info, whilst skill being performed
bigger the schema the more efficient the movement
feedback is important
what is the recall schema
-quick movements
- consitis to all the info needed to start relevant movement
- this includes knowledge of court, surface and postion
performed with no feedback
what are the two sections of the recall schema
knowledge of environment
response specifications
what happens in the knowledge of environment in recall schema
consider playing conditions
positions of the team mates
condition of equipment
what happens in the response specifications in the recall schema
speed and force required
size and shape of movement
techniques and styles used
what are the two types of schema
recall
recognition
what happens in the recognition schema
info needed to correct errors and remember correct performance
info about evaluating response
snesory consequences- feeling+look
response outcome- results of performance
ways to improve schema
perfect practice makes perfect
repeat skill
repetition of any info or skill will enable to be remembered
